In Caddisflies, Gary LaFontaine attributed the famous spring hatch on the Beaverkill (now known as the "Apple Caddis") to this species. After that publication, entomologists described that major hatch as a new species -- Brachycentrus appalachia.

Brachycentrus numerosus is probably still important in many locations.
